Letters Patent No. 78,673, dated June 9, 1868.

tlfl'm it W idetrieiarsrri new r w TO ALL WHOM IT MAY CONCERN: y I

Be it known that I, ZENo KELLEY, of New Bedtovd,in the county ofBristol, and State of Massachusetts, have invented certain new anddseful Improvements in llarpoons; andI do hereby declare that the l w ga full, clear, and enact description there of, reference being had tothe accompanying drawings, and to the letters of reference markedt'hereon, which form a part of this spe cilieation, in which-.-

Figure 1 is a plan view of my harpoon. I

Figure 2 is a longitudinal section of the same. I, v

The letter A represents the shaft of'my'harpoon, and is formed, twosections, a and d, 0 having a hole in its lower end, in which' the upperend of section is made lit.

The section dis reduced in size from the point a to the end thatconnects it with section 0. The object of this reduced portion of d isto receive the slide e, which is allowed to play hetween'the point sandthe adjustable shoulder t.- Betweenthe shoulder tand slide easpiralspring is placed, the object of which will be lxei-eafter seen. vI

E represents the harpoon-head, which fits in a socket at the lower endof section 12.

In the neck at the harpoon-head which enters d, as above described. apercussion-cap, o, is inserted, the head itself being filled withgunpowdc n v p i I In order to explode the powder by the agency of saidcap, the following devices are used: First, the crossbar 9, which ispivoted in slot 12. The said bar may he so constructed as that its lowerend will be flush. with the side of the harpbon, so that it wi'i'lgivenoresistonoawheaeenteningthe.whale.thenunirer en glpf V y being madeto project sufliciently far above the section 11 as that's, cordattached to said section will draw the said bar at right angles to theharpoon, and, by its resistance, prevent the whole 'from' escaping. Thebar 9 has on its upper edge the pin 1', the cflice 'ofwhich will behereafter seen.

V represenijs' the hammer which explodes the cap. The said hammer isprovided with a cylindricalrod, j,

which extends in the direction of bar g, as seen in fig. 2. Near theendof'suidl'od the pin a is inserted, the

said pin serving the purpose of keeping in place the metal plate m. J

The plate m, it will he observed, has a hole near its'inner end, whichis intended for theadmission of pin 5 whem the harpoon is prepared forstriking a whale. I it represents a spiral spring, which is placeddirectly behind the hammer V, and designed by its action to give thehammer suflicient momentum to explode the cap.

When preparing to strike a whale, the f llowing operations are to beobserved: Theharpoon-headbeing charged with powder, the plate 1 must bepushed back until the pin 11 will enter the hole in said plate. Inpushing back plate m, the cylindrical rod j, with hammer V attached toit, will be drawn back by the action of pin a. The drawing back thehammer V will compress the spiral springhand keep it in position to acton the hammer when required. Cords now being inserted through the holesin slide e, the harpoon may be thrown by hand, or, if desired, section 0can be inserted in a gun, and the' harpoon shot into the whale. -Whenthe point of the h,arpoon has penetrated the fish as far as the lowerend of bar g, the said end will be forced out, the pin a" released fromthe hole in m, and spiral spring B, being left force against the cap 0to explode the powder in the harpoon-hcad E.

The sections 0' and 01 will be uninjured, and can he used again. I

Figure 3 represents the iron breech-pieceL, with an elliptical spring,f, attached to it, which can beplaeed against the shoulder to break theforce of the recoil when a gun is used to discharge the shaft.

It will be remarked that a balLmay be inserted in the head E with thecharge of powder; and furthcn that a gum-elastic or spiral spring may beused for the breech-piece.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

The hammer V, spring h, rod j, pin a, and bar g, incombination with headE, all purpose set forth.

In testimony that I claim the foregoing as my own, I chi; my

free to act, will drive the hammer V with sufiicient aignatnreiiipresence of two witnesses.
